Our welding fluxes

Sandvik’s welding consumables acquired by ESAB

Sandvik’s welding consumables business has been acquired by ESAB from February 1, 2018. Over the coming months ESAB will be integrating the Sandvik portfolio, to provide a smooth transition for customers. During the integration period, the full line of Sandvik welding products will continue to be accessible on this website, or via the ESAB website.

Flux for submerged-arc welding (SAW)
Flux Characteristics Applications
Sandvik 10SW Cr compensated
Basicity 1.0
General purpose flux for both strip and wire electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized. Good slag removal. Gives about 2% higher ferrite content than 10S.
Sandvik 15W Non-Cr compensated
Basicity 1.7
Special purpose flux for wire electrodes of Cr-Ni and CrNiMo steels, stabilized or non-stabilized as well as duplex, super-duplex and fully austenitic grades, e.g. 20.25.5.LCu. Good slag removal. Gives good impact properties. The Nb burn-off is very small when using stabilized electrodes, such as 19.9.Nb.
Sandvik 31S Non-Cr compensated
Basicity 1.1
Single purpose flux for both strip and wire electrodes of 25.22.2.LMn, intended for urea applications. Good slag removal.
Sandvik 34S Cr compensated
Basicity 0.85
A neutral slightly chromium compensating welding flux for submerged arc welding giving good slag removal and fine bead appearance. Suitable for surfacing with strip and wire electrodes and can also be used for joining.
Sandvik 50SW Non-Cr compensated
Basicity 2.4
General flux for strip and wire electrodes of nickel alloys. Good slag removal.
Flux for electroslag welding (ESW)
Flux Characteristics
Applications
Sandvik 37S Non-Cr compensated
Basicity 3.8
General purpose flux for strip electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized, duplex and fully austenitic grades, e.g. 25.22.2.LMn. Excellent slag removal and bead appearance.
Sandvik 47S Non-Cr compensated
Basicity 4.0
General purpose flux for strip electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized as well as duplex and fully austenitic CrNiMo grades, e.g. 20.25.5.LCu. Excellent slag removal and bead appearance. Low Si pick up.
Sandvik 48S1) Non-Cr compensated
Ni alloying
Basicity 4.0
Special nickel alloying flux for strip electrodes of mainly super-duplex type.
Sandvik 49S Non-Cr compensated
Basicity 4.4
High speed flux for strip electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized. Excellent slag removal and bead appearance.
Sandvik 57S Basicity 4.0 Flux for strip electrodes of nickel alloy type giving excellent slag removal and bead appearance.
Sandvik 59S Basicity 5.0 A highly basic, agglomerated flux for electroslag strip surfacing. Used together with strip electrodes of nickel alloy type.
Sandvik 69S Non-Cr compensated
Basicity 5.4

Highly basic, agglomerated flux for electroslag strip surfacing. Specifically designed for high speed welding of nickel based alloys
